Congressman Rodney Davis is calling on his opponent’s supporter, Emily’s List/Women Vote, to remove what he says is a negative TV ad featuring his children.

The ad says Davis wants to gut protections for people with pre-existing conditions and features their three children. Davis’ wife, Shannon, has a genetic form of colon cancer that could also be passed down to their children, according to the Davis campaign.

“In my book, kids are off limits in politics and it’s appalling to me that this outside group, who is spending nearly a million dollars in support of my opponent, would use my children in a negative TV ad against me,” Davis said Thursday. “My opponent has spoken about her son several times throughout this campaign and I would never use him, nor condone an outside group using him, in a negative way to make a political point.”

Davis is facing Democrat Betsy Dirksen Londrigan of Springfield in the 13th Congressional District race in November.
